Background. First-line therapy does not always provide a high level of Helicobacter pylori eradication due to the increase of H. pylori resistance to antibiotics; therefore, it remains necessary to identify the most effective rescue treatments. The purpose of this study was to evaluate the efficacy and safety of empirical H. pylori furazolidone-containing regimens. Materials and methods. Adult H. pylori infected patients empirically treated with furazolidone-containing eradication regimens were registered in an international, prospective, multicenter non-intervention European registry on H. pylori management (Hp-EuReg). Data were collected at AEG-REDCap e-CRF from 2013 to 2021 and the quality was reviewed. Modified intention-to-treat (mITT) effectiveness analyses were performed. Results. Overall 106 patients received empirical furazolidone-containing therapy in Russia. Furazolidone was prescribed in a sequential scheme along with amoxicillin, clarithromycin and a proton pump inhibitor in 68 (64%) cases, triple regimens were prescribed in 28 (26%) patients and quadruple regimens in 10 (9.4%). Treatment duration of 7 days was assigned to 2 (1.9%) patients, 10-day eradication therapy in case of 80 (75%) and 14 days in 24 (23%) patients. Furazolidone was mainly used in first- (79%) and second-line (21%) regimens. The methods used to diagnose H. pylori infection were: histology (81%), stool antigen test (64%), 13C-urea breath test (6.6%), and rapid urease test (1.9%). The mITT effectiveness of sequential therapy was 100%; 93% with the triple therapy and 75.5% with quadruple therapy. Compliance was reported in 98% of cases. Adverse events were revealed in 5.7% of patients, mostly nausea (3.8%). No serious adverse events were reported. Conclusion. Furazolidone containing eradication regimens appear to be an effective and safe empirical therapy in Russia.

Recently, there has been an increase in the prevalence of gastroesophageal reflux disease (GERD) in Northern Europe, North America and East Asia. However data on GERD prevalence in Russian population are very limited.To determine the prevalence of GERD among the population of Russia, the clinical spectrum of GERD symptoms, the main drugs used for GERD treatment, and the rate of their administration.The study was conducted from November 2015 to January 2017 in 8 cities of Russia. A survey of patients over the age of 18 years old visiting outpatient medical institutions for any reason, including patients without gastrointestinal complaints was carried out using a short version of the Mayo Clinic questionnaire.In total, 6132 questionnaires of patients aged 1890 years were analyzed [2456 men (40.1%) and 3676 women (59.9%), mean age 46.615.4 years]. The GERD prevalence among the interviewed patients was 34.2%. The incidence of GERD increased depending on body mass index and the age of the patients. Medications used by the patients for heartburn relief included proton pump inhibitors 59.96%, antacids 67.92%, H2-histamine receptor blockers 11.42%, alginates 18.41% of patients.The results of this study indicate a high prevalence of GERD among residents of Russian cities applying for primary health care (34.2%). In comparison with previous studies, an increase in the proportion of GERD patients taking proton pump inhibitors was noted; in most cases the regimen of their intake was in accordance with the recommendations.Обоснование. В последние годы отмечается увеличение распространенности гастроэзофагеальной рефлюксной болезни (ГЭРБ) в странах Северной Европы, Северной Америки и Восточной Азии. Данные о распространенности ГЭРБ в российской популяции весьма ограничены. Цель. Определить распространенность ГЭРБ среди населения России, клинический спектр симптомов ГЭРБ, основные лекарственные препараты, применяемые для лечения заболевания, и частоту их приема. Материалы и методы. Исследование было проведено в период с ноября 2015 по январь 2017 г. в 8 городах России. Проводилось анкетирование пациентов старше 18 лет по короткому варианту опросника клиники Мэйо, посещавших амбулаторные медицинские учреждения по любой причине, в том числе не имевших жалоб со стороны органов пищеварения. Результаты. Всего проанализировано 6132 анкеты пациентов в возрасте 1890 лет [2456 (40,1%) мужчин и 3676 (59,9%) женщин, средний возраст 46,615,4 года]. Распространенность ГЭРБ среди опрошенных пациентов составила 34,2%. Наблюдалось увеличение частоты ГЭРБ с повышением индекса массы тела и возраста пациентов. Наиболее часто для купирования изжоги и регургитации опрошенные пациенты принимали ингибиторы протонной помпы 59,96% и антациды 67,92%, реже блокаторы Н2-рецепторов гистамина 11,42%, альгинаты 18,41%. Заключение. Результаты настоящего исследования свидетельствуют о высокой распространенности ГЭРБ среди жителей городов России, обратившихся за первичной медицинской помощью (34,2%). В сравнении с ранее проведенными исследованиями отмечено увеличение доли больных ГЭРБ, получавших ингибиторы протонной помпы, при этом в большинстве случаев режим их приема соответствует рекомендациям.
